The fracture system was characterised using combined core logging and down-hole acoustic and optical televiewer imaging.

• Bedding-parallel fractures with a dominant ENE-WSW strike and dip of 2-29&Mac251; to the SSE and a subordinate bedding-parallel fracture set with E-W strike and N dip of 10-30&Mac251;

• High-angled fractures include sets with a ENE-WSW or E-W trend and NNW dip of 30 to 80&Mac251;, and sets with a NW-SE trend and NE dip of 35-75&Mac251;

• Mean fracture spacing for combined bedding-parallel and high-angled fractures is 0.23 m

• Fracture porosity is estimated as 1.1% and is similar to estimates from other studies
